This work aimed to quantify the production of mini stakes by mini stumps of Eucalyptus urophylla in relation to the collection of sprouts and concentrations of nutritive solution. The sprouts were originated from seminal mini stumps, cultivated in plastic pots capable to store 3.0 L, with openings at the bottom, with substrate composed of sand, thin layer, and fertigated with nutritive solution in three concentrations: 25, 75 and 100%, with the accomplishment of 6 collections over time. The production of mini stakes was conducted from a randomized block design with factorial arrangement (3x6) and plots subdivided in the time, with the factors being formed by nutritive solution (S1 – 100%, S2 – 75%, S3 – 25%) and collection of sprouts (6 collections), according to productivity. The annual production of mini stakes per square meter (NM) has significantly varied in relation to the nutritive solution, and the collections of sprouts and the results have shown oscillations over the six collections. The 100% solution and the 6th collection have obtained the greatest production of NM.
